Need JSP-URL in controlling servlet

Question

Hi,
I have a simple questions which is driving me crazy.
2 JSP's are using same Servlet which has to process their input.
Inside this servlet I need to know which jsp is calling the servlet.
I tried following code :
          System.out.println("req.getRequestURI() = \"" + req.getRequestURI() +"\"");
          System.out.println("req.getClass() = \"" + req.getClass() +"\"");
          System.out.println("req.getPathInfo() = \"" + req.getPathInfo() +"\"");
          System.out.println("req.getPathTranslated() = \"" + req.getPathTranslated() +"\"");
          System.out.println("req.getServletPath() = \"" + req.getServletPath() +"\"");
          System.out.println("HttpUtils.getRequestURL(req)= \"" + HttpUtils.getRequestURL(req) +"\"");
but none of them are returning the correct name of the calling JSP...
Here are the results in same sequence:
req.getRequestURI() = "/servlet/com.clipper.servlets.FQController"
req.getClass() = "class com.ibm.servlet.engine.webapp.WebAppDispatcherRequest"
req.getPathInfo() = "null"
req.getPathTranslated() = "null"
req.getServletPath(req) = "/servlet/com.clipper.servlets.FQController"
HttpUtils.getRequestURL()= "http://www.clippersupport.be:2031/servlet/com.clipper.servlets.FQController"
As you can see, I only retrieve the Servlets info, not the JSP's...
I need to find :
/JSP/JSP1.jsp
How do I do this ???

Answer 1

I don't think it is possible to find out the details of the calling jsp in another servlet jsp or servlet. The only possibility is in the jsp get requestURL and place this as a request parameter in the request. Then when you call the servlet, the servlet can then extract this request parameter.
